Please see my other patch instead.

You are using incorrect brace style, and I think your error message
is a bit misleading - "look up failed" sounds like some internal
error, the reason of which is still unclear.  We should instead say
clearly the the given device type is not supported/known in the
given configuration.

Thanks.

Best regards,

Wolfgang Denk
